Mahoney declares House bid

Former Republican National Committeeman Sean Mahoney announced Monday he's running against New Hampshire Rep. Carol Shea-Porter, blasting the Democratic incumbent as well as his own party in a video launching his campaign. "The Republicans are just as to blame for some of the mess we're in right now," he says in the message. "Over the last ten years, my Republican Party abandoned me as a conservative." Mahoney will compete in a primary with several other Republicans, including Manchester Mayor Frank Guinta and businessman Rich Ashooh. The former RNC official resigned from the committee last month ahead of a widely anticipated bid for the House.
